I've seen some sick designs for the outside, why not one for the inside? Where it scales with the ship in shape and form, where for instance the inside has 100 blocks inside per block outside for example, so we can walk around and even look through the windows in the "crew quarter squares" as a "screensaver" the view while we do something else, and have custom block designs for decorations, as well as for singleplayer, a bed where 1 hour is 10 min or 1 min in real time for us who doesn't have the game on a server to host the server, nor for those who doesn't have as much free time.
